unless:^ the `absorbent washer fits the 'spindle closely, the oil does not get evenly distributed on f `Paumfed Dec. 2o, 193s l PATENT OFFICE ,n 2,140,613 oIKLING Dliivioli` FOR DEAD- srINDLEs George rArragg, Lawrence, Mass. l Application November 22K, 1937, Serial No. 175,753 s claims. v(o1. vsos- 169) v xed at their bottom to a stationary rail.v There are approximately one hundred spindles on each Aslde' andfor each spindle there may be a cap or there Vmay be a ring, butin either case, there is a lifter railwhich causes to move up and down a tube slidable on eachvspindle. Each tube is re- 4voluble bymeans of a whirl at the bottom, each whirl being 'revolved by abandfin a well-known way.y Each spindle passes through a hole in the lifter rail and there is usually a recess surrounding this hole in which an absorbent washer is pilacefcl.Lv Extending over the recess is a metal lwasheron which the bottom or base of the tube` `andjofthe whirlrests. The base is'intended to revolve on the metal washer but they may revolve together and in either case,.centrifugal force tends to carry the oil outside onto the lifter rail where it may come incontact with the thread or the roving. Waste can also work in under the base I or' the washer and finally between the tube and f the `s`p'indle,'c`ausing friction and sometimes stopping the revolutions. f

As these tubes revolve'from five thousand to six thousand revolutions per minute, if one stops or slows up from improper lubrication, the thread on that bobbin is'slackand has less twist but the defect is hard to locate until it appears in the cloth'.r Uniform twist is very important. Toprovide the absorbent washers with oil, the tube or rthe tube and the Ymetal washer must be thje'spindle and as there is no way for the oil to mi. getfbetween the base'and the metal washer, they @tend torevolve together on thel lifter rail and this tends to throwoil out on'the lifter rail.

ffThe 'purpose ofv my device is toprovide a reservoir of'oil which will store enough for a week and at the rsame time will preventoil from getting out onto the stock or the yarnk or either getting in between the tube and the spindle. In this reservoir are absorbent washers of such a character that as the base of the tube and the whirl rests on and revolves' with a hard metal washer which rests upon and revolves upon two or more inwardly projecting lugs, the bottom of this washer and the top of the lugs are thoroughly lubricated at all times so that the friction is greatly reduced.

Preferably, all the revolving parts are inside the wall of the reservoir so that the oil cannot be thrown out. Preferably the top edge of the wall of the reservoir slopes in, and is close to or is outside of the bottom flange of the whirl, thus tending to keep the oil in and the thread and stock out. 'I'he revolving flange and the driving, both close vto the top edge of the reservoir, tend to throw outwardly any lint or loose thread or roving, thus keeping the inside of the reservoir entirely clear.

My whole device is simple and compact and the absorbent Washers can easily be replaced, while the metal washer can be made of hard metal and can be easily and inexpensively replaced when Worn. At theV same time, there is little if any wear on the base of the tube and the tube, therefore, will last longer.

'The construction also tends to alternately slightly squeeze and release the absorbent washers from pressure whereby the oil, while being evenly andthoroughly distributed where it belongs, is prevented from getting out onto the rails.

If there is a space between the top of the reservoir and the bottom flange of the whirl, the oiling can be done while the frame is in motion, although preferably it should be done when stopped, or if the wall is higher, the tube can be ,lifted andthe oil introduced below the flange.

My device comprises a tubular reservoir which rests on the lifter railoutside the Washer recess and having inwardly projecting lugs near but not at the top, there being the usual absorbent washer in the lifter rail recess and preferably two others of the same size below the lugs and also washer sections between the lugs extending up to the top of the lugs where there rests a metalwasher preferably always in contact with the washer sections.

As a result of this construction, the movements of the tube up and down on the spindle tend to suck the 'oil into the reservoir and as there are three and a, fraction absorbent washers instead of one, the frame needs to be oiled only once a week insteadof once a day.

As there are three and a fraction absorbent oily washer surfaces in contact with the spindle instead of one, the spindle and tube are kept better oiled and the washer sections keep the bottom of the 'bearing washer and the top of the lugs well lubricated so that whether the tube and whirl revolve on the washer or revolve with it on the lugs, everything is thoroughly lubricated. l

As the lugs and preferably the bearing washer are below the top of the reservoir, no oil can get out at the top and the roving or yarn cannot get inside the reservoir.

In Fig. 1 of the drawings, S represents a spindle carried by a rail A and carrying a tube T which includes the whirl 25 driven by a band 26 and having a base 2'I, the inside 28 of tube T being the same size as' spindle S so that tube T can revolve smoothly on spindle S and can be raised and lowered with the package of yarn P which .comprises a bobbin 83 on which yarn 8I is wound. The tube T is raised and lowered'on spindle S by a lifter rail L through which is a spindle hole I8 around which is a recess I9. i

The above parts as shown in Fig. l'represent thev type of spinning frame with which I prefer to use my oiling device, although it might be used with other types of spindles. f

The device as shown in Figs. 1 to 6, consists of a tubular reservoir R near the top of which the lugs I and 2 project inwardly. These lugs; are a sufficient distance above the bottom 4 to allowv two absorbent washers D and E to be below them and a suiiicient distance from the top 3 so that a bearing washer B can rest upon them and still the base 21 of tube T which rests upon washer B will be below the top 3. i

C represents the absorbent washer such as is Vnow often used in position in the recess I9 in the washer F. The total thickness of the washers C, D, E and F is such that they will slightly extend abovev the tops of the lugs I and 2, which tops are preferably substantially round.

The bearing washer B and the top Yof the lugs I and 2 are, therefore, lubricated and the movement of the lifter rail L has a slight tendency to compress rthese washers when going up but to produce a vacuum when going down. This action causes the oil to spread along the spindle S evenly but any excess is taken care of by the successive vacuum and compression and any oil which might beV thrown out at the bottom of the whirl 25 by centrifugal force is caught and held inside of and Y below the top 3 of reservoir R.

As vshown in Fig. 7, I may use in connection lwith reservoir 39, three inwardly projecting lugs 3|, 32 and 33 between which are the three sections 34, 35 and 36 of an absorbent washer.

Instead of making the bearing washer supporting lugs integral as are l and 2, I may, asshown in Figs. 8 and 9, use round plugs such as42, each with a conical rhead 43, vdriven into a conical hole 4I in the side of a reservoir such as 40.`

As shown in Fig. l0, lugs suchl as 46 can be spot' welded as at 48 to the inside of an inside tubular reservoir 4'1. Y

If necessary, as shown in Fig. 6, the top 'IV of the bearing washer such asB can be somewhat rough so that it will stick to base 21 but the bottorn 8 should be hard, smooth and flat so that it willslide easily on the top of the lugs. y

Instead of having two absorbent washers below the lugs, I may, as sho-wn in Figs. l1 and 12, use a reservoir 5B with lugs 5I and 52 between whichare sections 54 of an absorbentwasher, there being only one absorbent washer 53 Aunder the lugs. This washer 53 rests on the washer C in the recess in lifter rail L.

Moreover, as shown in Figs. 13 and 14, I'can'use a reservoir 6E) with lugs 6I and 62, between which are the sections of an absorbent washer 64, on which the bearing washer B rests. 64 rest directly upon the absorbent washer C in the recess in the'lifter rail L. The lugs 6I, 62 have wide bases, their sides are curved Vand the washer sections 64 are shaped to t. f

As shown in Fig. 2, the top 3 of the reservoir is closed to the bottom flange 9 of whirl25, but as shown in Fig. 15, at 83 it may extendoutside of it or as shown at 84 in Fig. 16 it may be below but close to it. K

In Fig. 17 I show a Vreservoir 8D of which the top part 8I slopes in so as to be under and close to the bottom outside edge of whirl 9. This permits of the use of a larger absorbent washer 87 under lugs 82 andof larger washer sections 85 between the lugs and also of a larger bearing washer 86 resting on the lugs. Y

By making the 'top of my reservoir sloping inward, any oil which maybe thrown out by the revolving whirl is caught and directed back into the reservoir while lint and especially any threadv which might be caught by the lower flange of the whirl 9 slips over the outside facev of the top instead of getting inside the reservoir.

To reduce theV friction, I have shown the topV surface of the lugs such as 2 and 42 as being a convex curved bearing face, butfI Vcan go beyond this and use revoluble bearing faces `such as balls or rollers as shown inFigs. 18, 19, 20 and 2l. v

In Fig. 18is shown a reservoir 'I6 with lugs such as 'II in each of which there are two sockets for balls 12, I2 which project at the'top, washer sections II and I2 and washer 'I3,and in Fig.` 19

'Ihe sectionsV se. l

` washer sections 95 which rest on an absorbent show a lug such as 14 in which are two rollers 15, 15 each in a suitable recess or socket.

In Figs. 20 and 2l I show a reservoir 90 in which ,Y sockets such as 92 each fora ball 93vwhich projects upward to serve as bearings for a bearing washer 91; There are also three holes 94 which extend through and in these are the cylindrical Washer 98.

I claim:
